DOOR-STOP.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed February 2' 1915. Serial No. 10,984.

To all whom it may concern Be it known that I, ALVIN E. HILL, a citizen of the United States, residing at Lawrencevillc, in the county of Lawrence and State of Illinois, have invented certain new and useful Improvements in Door-Stops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide a novel, eflicient and inexpensive door stop including a spring frame attachable to the lower portion of a door and an elastic ball rotatably supported in the frame and having frictional engagement with the floor to retard the swinging movement of the door.

Another object is the provision of a unitary supporting frame including a pair of spring arms in the outer ends of which the elastic ball is rotatably mounted and by which the ball is resiliently retained in spaced relation to the door so as to permit the ball to be moved inwardly toward the door against the tension of the spring arms when the door is swung against a wall or other relatively stationary object.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a fragmentary perspective View of the door, showing the stop applied to use thereon, and Fig. 2 represents a. diametrica-l sectional view through the ball, showing the frame broken away.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally the supporting frame of the door stop which is formed of a strand of spring wire bent centrally to define the inverted V- shaped door engaging or base portion 6 and having loops 7 to provide eyes to receive screws 8, or equivalent securing devices whereby the base portion 6 is rigidly se cured to a door or other hinged closure 9. The free ends 10 of the wire are extended downwardly from the loops 7 and outwardly with relation to the door 9 and the extremities 11 thereof are directed inwardly in alinement. The portions 10 of the wire constitute spring supporting arms for the cushioning element or elastic ball, to be hereinafter described, and are coiled at 12, intermediate the ends 11 and the loops 7, so as to increase their resiliency or tension.

The cushioning element constitutes a ball 13 preferably formed of rubber or other elastic material having a diametrical bore receiving a metallic bushing 14 which latter is rotatably mounted upon the alined ends 11 of the frame. The ball 13 is normally retained in spaced relation to the door 9 by the spring arms 10 and the lower extremities of the latter are prevented from spreading by a strap 15 having its ends looped and secured to the coils 12 of the arms.

In use, the stop is secured to the door in such position that the ball 13 is retained in rolling contact with the floor or fioor covering and thus the swinging movement of the door is retarded. It is clearly apparent that the elastic material of which the ball is formed insures against scratching, tearing or other injury to the floor or its covering as the ball is moved thereover. Should the door be swung against a wall or the like it is obvious that the ball 13 and spring arms 10 will engage the wall and thus resiliently retard the movement of the door and prevent injury thereto.

That I claim is:

A door stop comprising a frame formed of a single piece of wire bent intermediate its ends to provide an attaching portion, the ends of the wire being continued from the attaching portion and extended downwardly and outwardly therefrom and coiled, and then extended from the coiled portion and having their free terminals bent in the direction of each other, a cushioning element interposed between the extended ends of the Wire and having an In testimony WhereofI afiix my signature opening extendifiig therethrough for ldetachin presence of two Witnesses.

abl receivin t e bent termina s of t e ends of he Wire, and a strap extending trans- ALVIN HILL versely of the ends of the Wire and having Witnesses:

its opposite terminals connected to the coils, T. T. J ONES,
